IRQs being shared, is that a problem?

[Werdna]

Hi, I've read in a lot of your psts that you all try and make sure none of your IRQs are being shared, a fair few of mine are being shared, is that a bad thing?

IRQ 0 System timer OK
IRQ 1 Standard 101/102-Key or Microsoft Natural Keyboard OK
IRQ 2 Programmable interrupt controller OK
IRQ 3 Communications Port (COM2) OK
IRQ 4 Communications Port (COM1) OK
IRQ 6 Standard Floppy Disk Controller OK
IRQ 7 ECP Printer Port (LPT1) OK
IRQ 8 System CMOS/real time clock OK
IRQ 10 IRQ Holder for PCI Steering OK
IRQ 10 Intel 82371AB/EB PCI to USB Universal Host Controller OK
IRQ 10 Monster Sound MX400 Series Device Manager OK
IRQ 11 IRQ Holder for PCI Steering OK
IRQ 11 Matrox Millennium G400 DualHead Max - English OK
IRQ 12 Cordless8 (PS/2) OK
IRQ 13 Numeric data processor OK
IRQ 14 Intel 82371AB/EB PCI Bus Master IDE Controller OK
IRQ 14 Primary IDE controller (dual fifo) OK
IRQ 15 Intel 82371AB/EB PCI Bus Master IDE Controller OK

In practice IRQ sharing is only good when you don't use both devices at the same time, it just doesn't work well otherwise with 99.9% of cards [and drivers] out there.

So, you want your sound card and video card on separate irqs.

Werdna,
Your video card is alone on IRQ 11 as it should be. The only sharing you show is the USB controller and the sound card (don't worry about the IRQ holders, that's normal). This should not cause a problem. If your machine is working fine otherwise, don't worry and just leave things as they are. Everything looks OK as it is.
